.NET Fulltext Autocomplete In A Combobox?
Nov 2, 2011
I'm struggling to meet a demand from my supervisors.Basically there are places in our project where there is a big selection of options. The most concrete example is choosing a city in the world. The items are hundreds of thousands.Using standard winforms controls and properties, one can search through a list fast.The problem is that we're using a concatenation of city&district name for all the items. Essentially PREFIX autotomplete works but does not work as needed. The task is to filter and show items by any given string in any part of the item. Essentially a FULL TEXT search in the combobox.Does anyone have an idea about switching autocomplete sources in runtime relatively qiuckly and handling the suggest/suggestappend event?

I would like a fulltext autocomplete functionality for a Combobox. Built-in autocomplete only filters those items, that match the written text from the first letter. Is there any 3rd party components that has fulltext autocomplete? Or do I need to make functions myself?

I have a combox that is run-time bound to a table that is run-time built and populated from a text file. I have set the combobox autocomplete mode to suggest and the source to list items, but only the 1st item will work. Ok so here's the code:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
The file is a text file with a list of the 50 states and their abbreviations in the format : stateName - abbr.Now what happens is the data is displayed correctly, but when I begin to type a letter for the autocomplete the only letter that shows anything is the "a" and it will only show the very first item in the text file.Everything else does not display with the autocomplete, but does show in the list. I have tried variations such as adding the data as items like this:
Private Sub SetStateComboBox()
'set autocomplete for combobox
state_cmbx.AutoCompleteMode = AutoCompleteMode.SuggestAppend[code]....
This way does not allow any autocomplete when I begin typing but everything is in the list. I've also tried converting the table to a customautocompletestring and still the same results.The only way that I have been able to get it to work is be entering each state as an item: state_cmbx.items.add("Michigan - MI"), then it works correctly.Also the combobox dropdownstyle is set to dropdown, and I'm using visual studio 2010 ultimate and coding using VB.

I am having a problem to get the results of a combobox when the user uses the tab key to exit the combobox. The combobox uses a database as the datasource. When the user uses the mouse to click on the selection the selectedindex is set proprerly, however when the user will enter some text and presses the tab key, selectedindex is set to -1.
I have attached some test code to duplicate the issue.
Imports System.Data.OleDb
Public Class Form1
Protected dvNames As DataView
Dim conDBTest As OleDbConnection
[Code]....

I have tried searching on if it is capable to do autocomplete in a combobox in the datagridview control. I was planning to use the combobox in the grid itself. There is a property to set autocomplete true/false but I cannot get the cb to let me enter text to find. It only selects on the first character of items in the list.

I have a ComboBox which is bound with a DataSource from (obviously) a Database. However, there are 659 different entries inside this Database and I was hoping to tack on AutoComplete.
I tried setting the Source to the ListItems since, after initialization and the data is bound, all the items necessary are in fact inside the ComboBox so I had assumed that it would pick that up. I was wrong. I tried using a Custom source but VS errored out saying that I couldn't do that since the ComboBox was bound.
My question is, how can I utilize AutoComplete's "Suggest" mode with a bound ComboBox?

I am having issues with a combobox set to:
AutoCompleteMode = Append, AutoCompleteSource = ListItems.
Example: Items in the combo are: "Average", "Good", "Poor". If "Average" is selected in the combo, then I type "G", "Good" will autocomplete. But if "Average" is selected, tab out of the control, then tab back into the control, then I type "A" nothing is autocompleted. It just shows "A" in the combo.

I am having trouble with searching in my MySQL database. I do have FULLTEXT assigned to my table here is my code:
SELECT * FROM btt.btt WHERE MATCH(Solution) AGAINST ('the' IN BOOLEAN MODE)
this returns 0 results when in reality many results should have came back.I have read all the articles on the MySQL pages and it seems I am doing things correctly but obviously I am missing something.

With the initial loading of datagridview I could select an item with the combobox, but when I tried to select an item with other combobox I've got an error showing "System.ArgumentException: DataGridViewComboBoxCell Value is not valid. To replace this default dialog please handle the dataerror event" . When ever I click it's always shows this message.

I have some code that calls to Active Directory and gets a list of users then adds them into a ComboBox.
I would like to extend this feature by allowing the combo box to autocomplete when a user starts to type.
Ive read a few articles but they seem to be based on data coming from SQL server but none on Active Directory. Could anyone assist by advising how i could go about this?

I have a combobox that is populated with movies with a number corresponding to where it is held in our archives ie. "451 How The Grinch Stole Christmas"What I would really like to do is have an autocomplete routine that would make it possible NOT to have autocomplete only work on the first character. As it stands, with Visual Studio's native autocomplete if my combobox is populated by:
Apple Smoothie
Banana Puree
Crayon Colors
[code]....
and I type "Pu" I will get only "Pure Energy" as an autocomplete result. I would like it so that typing "Pu" would return Pure Energy & Banana Puree.

I have a couple of texbox and combobox controls that are bound to a dataset. I can scroll this with the a bindingnavigator. But I want to have the combobox do autocomplete from the dataset. For example, if i type a "D" in the combobox bound to the 'ClientName' column of the 'ClientInfo' table,i want the comcobox to display all (or maybe the top 20) names that start with a "D". If i then type an "E" I would like the list to show all names starting with "De" and so on.
I have tried to bind the 'autocompletesource' of the combobox to the 'ClientName' column, but that did not appear to do anything.I am reasonably experienced with VB .Net, but totally new to database and data centric applications.

I have a datagridview in vb 2010 and in one of the columns I populate a combobox with items from a database. With autosuggest, I filter the list to select an item. But autosuggest only works on the beginning of an item. I would like to search in each item. For example typing 'bank', I would like to select from:
Bank of Schotland
Deutsche bank
ING bank
Rabobank

I am building a autocomplete on my textbox. Really simple and it works really fine. But I like to do the next thing. When there is a match in the list and I will click on it. then i like to have a function.
For example
Private Sub ListItems_click(ByVal sender As Object, ByVal e As System.EventArgs)
MsgBox("test")
End Sub
How can i make this sub??

I use combo boxes with the Autocomplete turned on (Source = ListItems and Mode= SuggestAndApplend). The problem is that if the user stops typing for two seconds and then continues typing, the Autocomplete starts matching only on a new characters being typed. For example, I have a list with two items: "apple" and "please". I type "ap", then pause for a couple seconds and then continue typing "ple". I want the list to match on "apple" but instead it matches on "please". I'm looking for a property or some way to set the length of time the control resets the matching. Do you know if one exists?

Can we make a particular column in DataGrid to behave like text box AutoComplete mode?In the GUI, am planning that the user will select a ProductName and will enter the details in the datagrid.The problem I am facing is am not able to set datagrid column to AutoComplete.If I use Textbox or Combobox for the purpose, am not able to enter the selected content into the datagrid because the datagrid is binded to a dataset.
